Specication -of Letters Patent.

Application led August 16, 19,12. Serial No. 715,372.

To all whomt't may concern:

Be it known that I, JACOB GocEL, .a cit1- zen of the United States, and a resident of Toledo, in thel county 4of Lucas and State of Ohio, (post-oflice address, N o. 236 South Erie street, Toledo, -Ohio,) have invented a certain new .and useful Tire-Heater; and I do hereby decla-re the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specifica-tion. Y

My invention relates to tire heaters, and particularly td those lof the 4.gas burning type, but is not restricted to such use as it may be used in any connection for which it er the parts thereof may be adapted or appropriate.

.Theobject of my invention is the provision of an improved heater of the character described, which is simpleand eflicient in its construction and operation, and easily and quickly adjustable and regulable to suit tires of -diierent widths and diameters, and

which isadapted tomix the air .and gas at ably attaching the .point of combustion, thus preventing liability of back-firing Iand explosion-within the burner and .supply connections thereto.

The invention is fully described in the following specication, and while, in its broader aspect, it is capable fofembodiment in numerous rforms, a vpreferred embodiment thereof is illustrated in the accompanyingl drawings, in which,-

Figure l is a ,perspective view of a tire heater .embodying my invention. l? 2 is an enlarged central vertical section of a burner of the apparatusfrom front to rear thereof. F ig. 3 is a section on the line w, in Fig. 2. Fig. 4 is an enlarged plan of onehalf of the apparatus ,and F ig. 5 is a view 0f the apparatus shown in Fig. 4,1a part of which is 4shown in elevation and a part is shown as a central vertical section thereof.

:Referring to the drawings, 1 designates the tabl-cof the heater and is shown as beingmade up .of a plurality of sectoral sections 2, which have their side edges fitted closely together to 'coperate to form a circular table and are retained in assembled relation by an external uniting band 3, and by the .bolting .together or otherwise suitof the abutting downwardly the edges of the adjoining sections, as best shown in Fig. 4. The table 1 is supported l in its proper osition b a lur-aflit of leOs 5, which deneiid therefrdm.1D y D A burn-er 6 is mounted on the table 1 for each of the lslots 4 therein and has its air and gas lsupplying parts working downward through the registering slots 4 for longitudinal movement therein as the burner is radially shifted to suit the diameter of the tire to be heated. erably .of multiple story construction with control valves for each story thereof to enable -on'e or more of the stories to be used at a time as the width of the tire being heated may require. In the present instance each burner is shown as comprising a face plate or block 7, preferably of re-briclnwhich .is carried by a casing part 8, on the rear side of which casing part is provided a gaschamber 9 for each story of the burner, such chambers being arranged in superposed order .and connected by passages 10, in each of which .is loca-ted a plug or other suitable form .of valve 11. One of these valves is also located in the nipple 12 which projects downward .from the lower gas-chamber 9- through the registering A'table slot 4, 'and has connection through a -hose or`pipe 13 with a manifold or supply pipe 14, which extends around the base portion of the 1apparatus being attached to the legs 5, and has a valvecontrolledconnectic-n with a suitable source of gas supply. 0n the back of the casing which forms the gas-chambers`9 and communicating parts is secured or form-ed a casing part 15, which provides a transversely Abroadened airechamber 16 at the rear of acopio form to .adapt them to shorten and These burners are pref- A ratenteanec.3o,1913.

sov

and are of sectional telepipe 22,

lengthen as the burners are radially adjusted relative to the table center. The distributing head 21 has its bottom preferably of downwardly-projected conical form with a pipe 22 leadin to the center thereof from any suitable air blast creating means, and the top of such head is also preferably of inwardly ,projected conical form with its apex in axial vertical register with the air 1, inlet opening of the 'head to cause the blast,

which is discharged into the head from the to be equally distributed` to all sides of the head, whereby all burners will receive an equal supply of air.

Each gas-chamber 9 of a burner has a plurality of discharge nozzles or tubes 23 extending forward therefrom through the plate or block 7 and each air-chamber 16 has a plurality of discharge nozzles or tubes 24, projected forward therefrom through the gas-chamber 9 in advance thereof and into registering gas-discharge nozzles 23, an air nozzle 24 being provided for each gas nozzle 23. The nozzles 23 and 24 are in concentric spaced relation, with the air-nozzles 24 preferably terminating short of the discharge ends of the gas-nozzles 23, whereby the discharge of gas from the respective gas chambers through thenozzles 23 around the air nozzles is augmented by the discharge of air from the nozzle 24, las is apparent, the mixing of the air and gas taking place at the point of combustion instead ofbeing mixed in bulk within the burner before discharging the same therefrom. The miXin of the air and gas without the burner an at the point of combustion prevents backring and explosions within the burner, and supply connections, thus overcoming an objectionable feature which is present in burners of this class commonly employed.

The face of each burner is provided at its top and bottom edges with inwardly projecting segmental flanges 25, and intermediate such flanges with a plurality of inwardly projecting spacing studs 26 which are intended to coact with the periphery of a tire being heated to prevent the burners from being moved too close to the same. The flanges 25 tend to confine the flames from the burner in the space between the faces of the burners and the tire.

In the use of my improved tire heater, a tire is placed upon the table 1 within the burners 6 and the burners adjusted to properly space them from the tire. Should the tire be too small for all of the burners to be moved inward to properly spaced position relative thereto, alternate ones of the burners may be inwardly `adjusted for such purpose. Before turning on the gas and air blast, the valves 11 and 18 of the burner, or certain ones thereof, are regulated to admit gas and air to all of the chambers 9 and 16,

or certain ones thereof, as the width of the tire to be heated may require, thus adapting the burners to operate as an entirety or enabling a cutting off of one or more of the upper sections, as desired. This being done the gas and air are turned on, causing gas to be discharged from the burner chambers 9 through the nozzles 23 and air to be discharged from the chambers I16 through the nozzles 2&1, the mixture and combustion of the air and gas taking place without the burner.

1t is found in practice that this construction of burner and the manner of discharging the gas and air therefrom provide `a powerful blast furnace or heater which effects a rapid heating of a tire to the desired temperature. y,

The building of the table in sections enables the same to be quickly assembled or knocked down and compactly packed for shipping or storing, and also enables the several parts thereof to contract or expand under changing temperature conditions without breaking. The band 3 which encircles the periphery of the table permits the table to expand when heated.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

1. A gas burner having a vertical face, a plurality of superposed communicating air chambers and a plurality of superposed communicating gas chambers, said air and gas chambers .,coperating in pairs to form operative burner sections each having a discharge nozzle in said face, and means controlling the flow of air and gas to the respective chambers.
